Things to Consider When Shopping for Parts & Maintenance

When shopping for Parts & Maintenance, the most important thing to consider is what your bike actually needs. Whether you're replacing a worn component, protecting your frame, or sourcing parts for a custom build, it helps to start with a clear idea of the job at hand. Drivetrain parts are among the most commonly replaced items, so knowing your bike's groupset compatibility will save time and ensure a proper fit. Frame protection is worth considering if you want to guard against scratches, cable rub, or trail debris over time. Skewers may seem like a small detail, but choosing the right type for your wheel and dropout style matters for both safety and performance. This collection covers everything from routine upkeep to individual replacement parts, making it a practical stop for riders who prefer to service their own bikes. Explore the different types of Parts, Components & Maintenance Products below to find the right fit for your riding needs.

Commonly Asked Questions about Parts & Maintenance

How do I know which parts my bike actually needs?

The best starting point is identifying what is worn, damaged, or underperforming on your current setup. Common items that need regular replacement include drivetrain components like chains, cassettes, and chainrings, as well as smaller parts like skewers and frame protection. If you are unsure, a quick inspection at your local 99 Bikes store can help you identify what needs attention before you buy.

What drivetrain parts are most commonly replaced and how do I know if mine need replacing?

Chains, cassettes, and chainrings are the most frequently replaced drivetrain components, as they wear together over time through regular use. Signs that your drivetrain needs attention include skipping gears, chain stretch, or difficulty shifting smoothly. Replacing components in a timely manner helps prevent accelerated wear on other parts of the drivetrain, saving you money in the long run.

How do I make sure replacement parts are compatible with my bike?

Compatibility depends on several factors including your bike's groupset brand, the number of speeds your drivetrain runs, and your frame's dropout or axle standard. Checking your existing components for brand and speed markings is a good first step before purchasing replacements. If you are unsure, bringing your bike in or noting down your current groupset details will help you find the right match.

What is frame protection and do I really need it?

Frame protection refers to adhesive films, guards, or wraps applied to high-wear areas of your frame to prevent scratches, cable rub, and damage from trail debris. It is particularly useful on areas like the chainstay, top tube, and around cable routing points. While it is not essential, it is a low-cost way to preserve the condition and resale value of your bike over time.

What should I consider when choosing skewers for my bike?

Skewers need to match your wheel's axle type and your frame's dropout style, so it is important to check compatibility before purchasing. Common types include quick-release skewers and thru-axles, with thru-axles generally offering greater stiffness and security for modern bikes. Choosing the wrong skewer type can affect both safety and performance, so getting the right fit matters even though skewers
